I define it because I want to know what I am aiming at.
How do we define innovation and why should we? My current definition of innovation is: Newness that proves its worth.
The term innovation comes from the Latin word innovatus, which means “into the new”. So, innovation has movement or change that brings about “newness”. In addition there is an implicit element that exists in the modern use of the term. It is the idea that it must add value, whether to a company, society, government, or whatever context. The Latin root of value is vale, or val, strength and worth respectively. So, when ”newness” is created the change it causes must prove its worth. It must be strong enough to stand the test of time, and only things that people adopt and use, as a part of the fabric of their lives, will prove themselves truly valuable.
